Filter by:The objective of this study is to examine whether ABO and Rhesus (Rh) blood group systems have an association with distortion product otoacoustic emission (DPOAE) and transient otoacoustic emission (TEOAE) amplitudes with the hypothesis of blood groups may affect hearing thresholds.
The proposed field trial will clarify the real-world effectiveness of HAs in remediating deficits in emotion processing for older adults with mild-to-moderate hearing loss. This study will employ a repeated reversal design to establish baseline affective state without HAs, when wearing amplification, and after HAs are removed. This study will triangulate self-report, behavioral, and physiological measures to capture nuances of emotional processing in the laboratory and in daily listening. Naturalistic stimuli will be used as it occurs in daily life to elicit emotional experiences, and ecological momentary assessment and commercially-available wearable sensors will be used to track changes in emotional state in daily listening. Anchoring real-world emotional experiences with controlled laboratory experiences will validate wearable sensors. Additionally, laboratory emotional stimuli will be related to real-world emotional experiences to establish the utility of laboratory stimuli in future studies. It is likely that benefits in emotional processing will have differential effects based on individual characteristics (such as degree of hearing loss, age, gender, cognitive ability, and personality), so participants will be analyzed according to larger groupings based on individual differences.
Cochlear implantation (CI) allows rehabilitation for patients with severe to profound hearing impairment. Although the use of a robotic assistant provides technical assistance to the surgeon, the assessment of the impact of its use on auditory outcomes remains uncertain, due to inter-individual variability of preoperative audiometric thresholds and the various possible intrascalar positions of the electrode array. WThe investigators aim to compare the hearing results of patients who underwent bilateral cochlear implantation, one side was performed with manual insertion and the other side with robot-assisted insertion. The electrode array intrascalar positioning and the surgery duration were also studied. This retrospective intra-individual study involved 10 patients who underwent bilateral cochlear implantation. The unique composition of this cohort enabled the investigators to utilize each patient as their own control.
An observational study to determine and assess perception of prosodic information in adults who use bimodal stimulation (cochlear implant plus hearing aid) when using both devices vs. cochlear implant alone.
Steroids are used widely for the treatment of Sensorineural hearing loss worldwide. The difficulty lies with efficient delivery of the drug into the cochlea, which is already a sealed chamber with limited blood supply that too with an end Artery. We intend to extrapolate its effects by combining it with Platelet rich plasma. intra-tympanic delivery is achieved with injection via tympanic membrane and its absorption via round window is hastened by posture maintenance for about half an hour. PRP is an autologous biologic fluid which has excellent safety profile and is already in use by various specialties.
Subjective listening effort and objective speech intelligibility will be evaluated with a new generation of a Phonak BTE (Behind-The-Ear) hearing aid.
Internal research on the manufacturer's hearing aid products has idenitfied areas in which the investigators can improve the hearing aid frequency response curve. Based on the conclusions of the first study, we have identified areas that require further analysis and testing prior to implementing of the proposed frequency response curve into our products. This study aims to investigate the current freqeuncy response curve in the manufacturer's products to variations of these curves to determine if hearing aid users prefer the variations over the manufacturer's standard curve.
Pre-market Clinical Investigation whose primary purpose is to evaluate efficacy and effectiveness of self-fitting hearing aids
